SWITCH-STAN D.

SPECIFICATION forming part of Letters Patent No. 734,042, dated July 21, 1903.

Application filed May 11, 1903.

To all whom it may concern:

Be it known that LALVA B. BULLOOH, a citi zen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Switch-Stands; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in switch stands and throws for railroad-switches.

The object of the invention is to provide a device of this character which is simple in construction,,durable in use, efficient in operation, and comparatively inexpensive of production.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of my improved switch-throw. Fig. 2 Fig. 3 is a vertical longitudinal sectional View. Fig. 4 is a detail sectional view through a portion of one end of the casing, showing the guide for the locking-pin.

Referring to the drawings by numerals, 1 denotes a cast-metal housing or frame which comprises the 'semicylindrical portion 2 and the horizontal base-flanges 3, by means of which the castingis secured upon a suitable foundation adjacent to the railroadrtrack. Extending longitudinally through and slidablyjournaled in the semicylindrical portion of the housing is a shaft 4:, one end of which is swiveledor loosely connected to the rod 5, which moves the switch-point. 0 denotes an operating-lever one end of which is fixedly secured to the shaft 4 within the housing, and the free end thereof is provided with the weight 7. Said operating lever projects through and travels in an angularly or diagonally arranged slot 8, formed in the top of the semicylindrical portion of the housing or frame It will be seen that by throwing the operating-lever to either side of the housing Serial No. 156,650. (No model.)

the shaft 4 will be partially rotated and at the same time moved longitudinally to operate the switch-point through the connectingrod 5.

In order to hold or look the parts in either .position, the'shaft is provided with the openings or apertures 9, which are adapted to be engaged by thevertically-sliding lock-pin 10. Said pin slides in suitable guides 10 upon 'one end of the housing and projects through the top of the same. Its upper end is formed with an eye 11, which is adapted to register or aline with an eye 12, formed upon the top of the housing, so that the bail of a padlock or other fastening device may be passed through said eyes to lock the pin in engagement with the shaft. In order to actuate the locking-pin 10, a foot-lever 11 is pivoted between the integral lugs 12, formed upon the end of the housing. Said foot-lever has its inner end projecting through an opening in the end of the housing and is connected by .a link or rod 13 to a lug formed upon the lock-pin 10. By depressing the foot-lever 11 it will be seen that link 13 will elevate the pin 10 and free it from engagement with the openings}? in the shaft 4:.

14 denotes a vertical target-shaft which is journaled in the integralbearing 15 upon the housing. Oollars 17, secured to said shaft upon each side of the bearings, prevent the vertical movement of the shaft. 1 Upon the upper end of this vertical shaft is a sleeve 18, which carries the target-wings 19. A bolt18, passing through said shaft, sleeve, and the target-wings 19, secures said parts together. In the upper end of this sleeve is a plug or bar 18*, having a beveled upper end tofit in the bottom of the switch-lamp. Saidplug is secured in the sleeve by the bolt 18, which also passes through the red and white target-wings 19. The lower end of the vertical targetshaft 14 within the housing is provided with a crank arm or portion 21, the end of which is provided with a 'bolt or pin 22, which projects through a slot 23, formed in an airm24, projecting from a loose sleeve 25' upon the shaft 4:. Said sleeve 25 can turn upon the shaft; but the set-screws 26 uponeach side thereof prevent any longitudinal or sliding movement upon the shaft. Theslotted arm 24: is held in engagement with the bolt or pin 22 by the nut or head 27 upon its end.

The operation of the device is as follows: The operator presses his foot down upon the outer end of the lever 11, which will raise the locking-pin 10, as previously explained, and unlock the shaft 4. The weighted operating-lever 6 is then thrown from one side of the housing to the other, and in this movement it will travel the diagonal or angular slot 8, and thereby impart a longitudinal sliding movement to the shaft 4 as Well as a rotary movement. The longitudinal movement, as explained, will operate the switchpointthrough the instrumentality of the connecting-rod 5, and the same movement of the shaft 4 will rotate .the crank end 21 of the target-shaft by means of the slotted arm 24, and thereby operate the target. When the foot-lever is released, it will permit the locking-pin 10 to drop into either of the openings 9 in the shaft 4 in order to lock the same.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificingany of the ad vantages of this invention.

Having thus described myinveution, what I claim, and desire to secure by Letters Patcut, is

1. In a device of the character described, the combination of aframe or housing formed with an angularly-arranged slot, at shaftjournaled in said frame, an operating-lever secured to said shaft and operating in said slot, a target-shaft journaled in said frame and formed with a crank end, and a connection between the first-mentioned shaft and said crank whereby the target is operated upon the movement of the first-mentioned shaft, substantially as described.

2. In a device of the character described, the combination of a frame or housing formed with an angularly-arranged slot, a shaft journaled in said frame and formed with lookingapertures, an operating-lever carried bysaid shaft and operating in said slot, a lockingpin to coact with said locking-apertures, a lever and connection between said lever and pin for operating said pin, substantially as described.

3. A switch-stand comprising a frame or housing formed with a diagonal slot, a shaft journaled in said frame, an operating-lever secured to said shaft and projecting through said slot, means for locking said shaft against movement, a loose sleeve upon said shaft formed with a slotted arm, a target-shaft journaled in hearings in said frame, a crankarm upon said shaft and coacting with said slotted arm, and an adjustable sleeve upon the target-shaft carrying target-wings, substantially as described.

4. A switch-stand comprising a frame or housing formed with a diagonal slot, a shaft journaled in said frame and provided with locking-apertures, an operating-lever secured to said shaft and projecting through said slot, a target, connections between said target and shaft for operating the same, a sliding locking-pin coacting with said locking-apertures, a lever pivoted to said frame, and a link between said lever and pin, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
